R ILWAY JOURNAL BOX.

AppIieationllledMay 12,

This invention relates to an improvement in the Construction of journ alboxes for railway bearings and the like. There are large quantities ofthese boxes in use of standard a size in both outer and inner dimensionsso as to fit the standard mountings for the same now in use and toreceivethe standard axles. Neithertheinner nor outer size of the journalboxes can be changed becauseo't the necessity for meeting these existingstandards. i v Considerable difiiculty has, however, been experiencedwith the present form ofjour nal box because of the narrowness of theledges which support the journal bearing or brassesj, "permitting thebrasses slipping off the ledge getting out of position with consequentdamage to the various parts i i j It is an object of the presentinvention to overcome this difficulty by providingin the journal boxeswider supports or ledges for the journal hearings, or brasses without,however, preventing the use of suclr improved boxes with standard caraxlesfland box mountings. v

A more specific object of the inventionis to provide a journal box oithe type de scribed, having instead otthe usual nai' ro-w continuousledge, a series of wider lugs or projections which on opposite sidesofthe box are staggered, the lugs onone side being opposite the spacebetween. the lugs on the opposite side, providing 'awide support onwhich the journal brass may rest and permitting the standard collaredcar axleto be passed in a zig-zag manner between said lugs. j Anotherobject of the invention to'proe vide a journal boxof the type describedwhich will permit'more efficient lubrication of the bearings t Variousother'objectsand advantages will appear as the description of theinvention proceeds. i; In the accompanying drawings {which illustrate apreferred form of embodiment of the invention:

box partly in section on the line 2--2 of Figure 1. j v

Figl 3fshows asectional view on the line 3-3of Figure l. i

Fig. & shows a perspective view of a brass or journal bearingol thetypeused in the box as shown; 1 f In the embodiment of the inventionillus trated in Figure 1 of the drawings a journal box is providedwithledges 11 and 12 projecting out from the sidewalls thereof inposition, to support the brasses; these ledges are provided withextended portions or lugs 13-14; and 15 as illustrated and p01 tionsoflesser width as shown at 16 and 17. The arrangen'ient of these ledges orlugs is such that each wide portion iso-pposed to a narrow portion inthe opposite member, and the spacing is such as to permit the collar 22on the axle 21 to move in a zig-zag manner past each lug. f "Theaxle 2 1with collar 22 is shown partially inserted in the box 10 of Figure 1. Itwill be seen that while the collar 22 might not pass the ledge members13, 14 and 15, if the sides thereof were in straight line, it ispossible with the ledges in the form shown by applying a rocking, orweaving motion w; the journal to move the collar alternately into andout of the narrow spaces between the ledges andto enable it topass thewider parts thereof. i

It will be understood that'once the collar 22Jl1as passed all the lugs13, 14 and 15, the axle may assume true relation to the bearings withthe collar-22 inside the inner lugs and the lugs extending, inwardlybeyond the edge of the collar butnot into contact with the axle portion21. f

In the assembledbearing as illustrated in Fig. Qthe edges 18 and 19ofthe brassQO rest upon thelugs 13, 14 and. 15 and the brassin turnrests upon the'axle 21, the weight of the car resting on the top of thejournal box. it it i The extra width ofthe ledges. 11 and 12 due to theprojection of the lugs 13, 1 1 and 15 effectively prevent the brass 20from slipping off' the ledges asoftenhappened with prior boxes,and thespaces 16 and 17 between the lugs, permits the lubricant which is packedin the bottom of the box to work up under the brass and then down overthe journal providing better lubrication than where the edges of thebrass rests on a continuous ledgeL In assembling the journal box on anaxle the axle is usually the stationary member and the journal box isweaved back and forth over the collar of the axle tocause the lugs to,

pass the collar.

It will be understood that the size and shape of the lugs 13, 14, 15,etc., may be varied, that, the collar 22 need not always be wider thanthe distance between the lu s 13,

14 and 15 and that various other modifications and changes may be madein the embodiments of my inventionillnstrated without departing from thespirit of the invention'or the scope of the appended claims,

Which are intended to cover the provision of wider brass ledges Withoutinterfering With the use of my journal box, with standard housings andaxles. V

I Having thus described my invention, what I I claim as new and desireto secure byLet ters Patent is asv follows:

1.; In a journal box of the class described, ledges extending along theinner walls thereof, the said led'es being of irregular width and'soplaced t at the wide portions on one will be oppositefto narrow portionsof the other; i f r I 2. In a journal box of the class described,

1 opposite ledges Within the wallsof the said box of such form thatalternating wide and narrow'portionsthereof will be. in the positionthat each wide portion of. one ledge is opposite to a narrow portion ofthe opposing ledge throughout the lengthof the said ledge members.

3. In a journal boxof the class described, internal, longitudinal sideledges having alternate recesses and. projections. therein and so placedthat the projecting portions of I for use with an axle having a collarthereon,

staggered spaced projections, on the opposite inner side. walls of saidbox in osition to support. abrass hearing from fa ing therebetween', thespace between the free edges of all the projections on each, side. beingless than the diameter of the, axle. collar, and the distance. betweenthe edge of any projection of one side for. .a distance equal to thethickness of the axlecollar tothe edge of the projection on the otherside being greater than the axle collar diameter.

6. In a journal box of the class described, equipped with fittings ofconventional pattern, and longitndinal shelf-like members on the innerside walls. thereof projecting inwardly beyond the journal collar, thesaid members being adapted to serve as retainers for a brass bearingmembers, and being so formed that their inner edge portions present anirregular alignment of such contour as to require the passing of thecollar of a journal member with a weaving movement when same isinserted.

7 In a journal box of the class described adapted to receive a collaredshaft, longitudinal ledge members located on the in ner side Wallsthereof, the said ledge members having flat top surfaces adapted tosupport a brass bearing member, and their inner side portions formedwith alternating projections and receding portions, the said projectionsand receding ortions so disposed that the base surfaces of the recedingportions are in line with the others of the same ledge, and the surfacesof the projecting portions are in similar alignment, the distancebetween the projecting portions being less than the diameter of theshaft collar.

8. In a. journal box of the class described, a casing, shelfdikelongitudinal projecting members within the said casing, extendinginwardly beyond the axle collar, the inner. portions of the saidshelf-like members presenting a broken alignment in which the narrowportions of each are opposed to, and of opposite. contour to the wideportions of the opposing member.

, 9. In a journal box of the class described an inwardly projectingledge on each side thereof in position to support; a brass bearing fromfalling therebetween, and wider than the standard ledges of said boxes,and means to. permit the journal box to be assembled on an axle having acollar of greater diameter than the distance between said ledgescomprising cut-away portions in staggered relation.

10. In a journal box of the class described, internally projecting meansextending into the center of said box and adapted to form ledges forsupporting brasscs, the effective interior extension of said meansleaving a less space than that required for a collared axle and means toinsert a collared axle therein.

In testimony whereof I have aflixed my signature to this specification.
